5 Claims.

This invention relates to laundry machines and has for its object the provision of improvements in clothes washing machines applicable primarily to domestic washing machines, whereby the construction is simplified, the number of parts reduced, the cost of important parts decreased, and improved certainty and safety of operation secured. The invention finds its greatest advantages in connection with those washing machines wherein the clothes are freed from adherent liquid by a centrifugal extractor.

Certain washing machines, mostly confined to an earlier day, were operated hydraulically from the municipal water pressure, but have proven unsatisfactory and largely gone out of use for two reasons: variations of water pressure which precluded successful operation at some places either always or occasionally; and municipal disiavor due to excessive use of water. These hydraulic machines have been largely replaced by electrically driven machines which wholly overcome the first noted objections but entail other peculiar drawbacks chiefly: (a) the necessity of some more or less complicated mechanical speedreducing, power-transmitting and motor-transforming appliances to adapt the regular rotation of the motor shaft to the purpose in view; (D) the high cost of the low speed motor which must be used if the mechanical problems are kept in proper bounds; (c) the positive nature of the mechanical type of drive coupled with the increase of mechanical advantage due to speed reduction renders such devices potentially dangerous to unskilled persons.

I have found that by a new and peculiar combination of the two systems, namely electric operation and fluid-pressure, I can avoid the defects of both, avoiding all uncertainty of pressure, all waste of water, all complicated gearing and much of the previous danger to unskilled persons, while enabling the use of a smaller and cheaper high-speed motor in place of the heavy slow-speed motor heretofore employed. Other objects and advantages of my invention will become apparent as the description proceeds. This application is a division of my former application filed November 3, 1927, Serial No. 230,753.

The device illustrated in Figs. 13 to 17 inclusive are the identical devices illustrated in my former application Serial No. 614,080, filed Janu-= my 22, 1923, and to this extent the present appli cation constitutes a continuation of said earlier case.

The combined washing and extracting machine illustrated in Figs. 1 to 5 inclusive of this application exhibits a casing formed with two upright compartments, 1 and 2, for washing and extracting, respectively. In its preferred form said casing comprises an upright sheet metal wall 3 conforming to the major portion of 'a cylinder intersected by the'upright wall 4 of the other compartmentwhich is itself generally partly cylindrical at least, there being a third upright wall 5 located between the two compartments and constitu ing a common partition extending from one intersection to the other of said vertical walls. Seamed to the lower edge of said side walls and partition wall is a bottom plate 6 mounted on a horizontal frame 7 carried by legs 8.

Mounted in vertical position in the external depends therefrom and extends loosely into an upright pipe 12 at the bottom oi which is a pump casing 13 in which is a pump rotor 14 carried by said shaft. The outlet conduit 15 from this pump leads to a suitable control-valve, which in the present embodiment comprises a rotatable turning-plug 16 fitting in a hollow casing 17 and provided with an operating rod 18 connected to a handle 19. The conduit 15 leads to the bottom of the casing 17 and is hence in constant communication with the hollow interior 20 of the valve member 16, the side'of which is formed with a port 21 adapted to be brought into register with one of the three ports 22 with which the side wall oi. the casing 1'7 is formed. Leading from these ports are three conduits 25, 26, and 27.

- The conduit 25 leads to a. fluid-pressure operating device for actuating the clothes washing mechanism; the conduit 26 leads to a hydraulic device for actuating the extractor; while the conduit 27 consists preferably of hose attached to a nipple 28 on the valve casing and enabling the liquid to be discharged at any desirable place.

The washing mechanism is of what I term the fluid-pressure operated rhythmically operating type, in which expression I include all fluidpressure operated devices whereby the clothes are periodically or intermittently, agitated or stirred, either directly by an intermittent hydraulic discharge or indirectly by an oscillating or reciproeating mechanical device actuated by fluid pressure. Within these limits the washing mechanism may take any suitable or desired form and in Figs. 1 to 4 inclusive, the washing device consists of an oscillatable dasher, comprising a circular metal plate 30 formed with one or more upright vanes 31, carried by an upright rock shaft 32 journaled in a sleeve 33 carried by the frame '7 and projecting into the bottom of the compartment 1, the lower end of the shaft being provided with a pinion 34 meshing. with a rack 35. This rack is operated by means oil a reciprocating hydraulic motor which in its present form, as illustrated in Fig. 4, comprises the following parts: 36 denotes a cylinder having at one 'end a packing box 37 in which fits slidably a piston rod 38 connected to the piston 39. Secured to the end of the cylinder opposite the packing box is the valve mechanism which comprises a cylinder head 40 cored to form two chambers 41 and 42 separated by a web 43 and formed, respectively, with the inlet port 44 and outlet port 45. Opposite faces of said cylinder head are also formed with alined pairs of openings 46, 4'7, and 48, 49, one pair for each chamber, and cooperating with said pairs of openings are the valve members and 51, respectively, which are connected by a yoke 52 so as to move together. The valve memher for the inlet chamber 41 has the valve heads inside of that chamber and work outwardly, while the valve heads for the outlet chamber are formed outside of that chamber and work inwardly. Secured to the yoke 52 is an operating rod 53 projecting through a hole'54 in the piston into a hollow bore 55 in the piston rod and terminating in a head 56, said rod being surrounded by a cushion spring 57 at each side of the piston. A longitudinal conduit 58 leads from the openings 47 and 49 to the opposite end of the cylinder. The conduit 25 is connected to the inlet port 44, while the outlet port 45 is connected with a conduit 60 leading to the inlet of the pump chamber and also to an upright open stand pipe 61 suitably located in some convenient part of the apparatus as for example inside the compartment 2 near one end of the partition 5. This stand-pipe accordingly constitutes a reservoir for the liquid in circuit to compensate for minor irregularities in movement between the pump and the pistons.

The extractor and also the turbine that drives it may also take any one of a great many forms. In the embodiment shown in Fig. 1 the extractor comprises a hollow frusto-conical container 62 larger at. the bottom than at the top, formed near the bottom with discharge apertures 63, and having in the center of its bottom a hollow boss 64 rising into the container and tightly receiving the vertical shaft 65 which is rotatably sleeved in the vertical bearing 66 secured to the casing 7 and rising into the compartment 2. Secured to the lower end of the shaft 66 is the rotor 67 of a suitable turbine whose casing 68 is formed with an inlet connected to the conduit 26 and an outlet connected by a pipe 69 to the bottom of standpipe 61 and thence to the pump 13. For washing purposes the compartment lis filled with washing liquid to the best washing level, which is preferably defined by a row of apertures 70 formed in the wall 5. The standpipe 61 is also filled with suitable liquid, preferably clean water, until it overflows at the overflow opening '71 provided therefor. The only reason for prolonging the standpipe 61 above the hole 71 is to facilitate filling the same, and the only reason for the hole '71 is that, being located below the top of pipe 12, it prevents accidental overflowing of the latter which would wet the floor. The motor 10 may be of any design which is properly mated to the pump but one advantage of the peculiar vertical mounting without stufling box is that instead of the usual 1725 R. P. M. it can successfully be operated at a much higher speed, so that the necessary power can be obtained by a smaller and less expensive motor. If the valve 16 be so locatedthat no port is open the water merely circulates in the pump chamber without doing any harm. When the valve is moved to connect the pump to conduit 25 the water passing through the inlet chamber 41 enters the cylinder 36 by way of whichever opening 48 or 49 is unobstructed, the contents of the opposite end of the cylinder being discharged through whichever outlet opening 47 or 46 is unobstructed. Arrived at the end of its stroke the piston compresses one of the springs 5'7 until the tension produced thereon is suii'icient to overcome the hydraulic pressure on the face of whichever valves are closed, whereupon the spring is suddenly released, moving the valve yoke to the opposite limit of its movement and reversing the liquid flow through the cylinder. As a result the agitator is oscillated at a fixed speed dependent upon the pressure of the liquid, the size of the cylinder, and the diameter of the piston. Any obstruction to its movement does little damage because of the fact that the pump is an impositive one. The standpipe 61 constitutes a reservoir to compensate for inequalities in the liquid flow at different parts of the stroke. Towards the end of the washing a few additional dipperfuls of waterare thrown into the compartment 1 to cause scum to be washed through the apertures 70 into the extracting compartment, after which the clothing is transferred to the container 62 and the valve 16 moved to open the port which leads to the conduit 26. By proper arrangement of valve ports it is possible to operate both the washing device and the extractor simultaneously, although ice lllllD with jet this requires a larger pump and a more expenwashing.

An arrangement including these modifications is illustrated in Figs. 6, 7, and 8 which show a casing formed with two upright compartments l and 2 for washing and extracting respectively. Said casing here comprises upright sheet metal walls 3 and i conforming to the major portions of two equal sized cylinders which intersect sym metrically iorming vertical solid angles at the two sides, the two compartments having an upright common partition 5 as before, and a bottom plate 6, frame 7, and legs 8. Parts 10 to 28 inclusive appear as before. In this embodiment, however, the washing mechanism comprises two jet-nozzles l5, l5 submerged in theliquid-holding portion oi the compartment 1* and connected to ports 76, It? formed at opposite ends oi the slidevalve-chamber 77 which is located crosswise along the lower margin of the partition 5. Located in this is the slidable valve member Z8 con nected by a lever it to a pitman so articulated to worm wheel til. which meshes with the worm on the shaft ll.

'* centrifuge in this embodiment comprises a us container 62 provided with an upall g vertical axial shaft 83 terminating in a sperical ball 8 received in a suitable soclret 85 by the bracket to. The bottom of the basket formed with turbine blades 67 coopernozzles 88 carried by the conduit Giving to the fact that the centrifuge container swings freely from the point 8%, l have shown two jet nozzles 88 located lilo apart to avoid any bodily displacement of the centrifuge. The extractor chamber 2 here talres the place of any stand-pipe and is formed with a drain opening 89 from which the conduit 60 returns the liquid to the pump.

Sufiicient washing liquid is introduced to fill the compartment i and also to maintain at all times at least a shallow layer in the compartment 2 As the motor and pump are operated the slide valve 78 is reciprocated to alternately open and close the ports "76, and when the valve 16 is also properly set a forceful stream of water is caused to issue alternately from the jet nozzles lb-l5, agitating the clothing and removing foreign matter therefrom, while scum and floating impurities are washed through the openings l0 but remain in the compartment '2, since the return to the pump leads from the bottom of that compartment. Further adjustment of the valve handle 19 directs the flow of water to the turbine blades 6'17 which causes rapid rotation of the centrifuge; while still further adjustment of the valve handle causes ejection of the liquid contents of the machine through the hose 27.

in Figs. 9 to 12 inclusive l have shown my improvements as applied to that kind of washing machine in which both washing and extracting talre place in the same container. In this ,i'orrn of the invention I have shown a casing 1 having a single upright cylindrical compartment carried by a frame 7 having legs 8, the frame having a rigid, upright, hollow sleeve 90 projecting a substantial distance upwardly into said compartrnent. Parts 10 to 26 inclusive are the same as before, excepting that in the present embodiment the shaft 11 is provided below the pump 13 with an extension ll carrying a second rotor 91 inside a second pump casing 92 whose inlet communicates with the bottom of the casing. l through a pipe 93 which can be closed by a stopper 9% carried by an operating rod 95.

Rotatably journaled on the exterior of the upper end of the sleeve 90 is a hollow hub 96 to the lower end of which is tightly secured the bottom 97 (in this case the double bottom) of the combined washing container and extractor. The sides 98 of this extractor-container are suitably joined to the bottom 97 and are preferably slanted gradually outwardly to a point between top and bottom, but nearer top than bottom, where they are provided with one or more rows of discharge apertures 99, said container being iniperforate below that point. Above the level of these apertures the diameter of the container is preferably decreased somewhat and the upper edge is preferably provided with a stiffening rim 100.

The hub is rotatable on the sleeve 90 and the bottom of the container is formed with turbine blades 5? surrounded by a casing 68 here carried by the sleeve 90, and provided with a drainpipe 6a which leads to the lower end oi the pipe 12, which in this embodiment takes the place and serves the functions of a standpipe or reservoir. The conduit 26 terminates in a nozzle 88 located in operative relation to the blades 5*2'.

Journaled in the sleeve 90 is an upright rocit shaft 16)]. having its upper end formed as at 102 for the reception oi. the soclret 103 of the dasher which has a cylindrical body portion ios terminating at its lower end in a circular disk 105 overlying the bottom of the container and formed with suitable blades lilo-l6? according to any desired pattern. Secured to the lower end or" the shaft 161 is a hydraulic oscillating device of any suitable kind which in the present embodiment consists of a kind of segmental pump. This comprises a hollow member having a cylindrical side wall lib terminated by circular end walls ill-4.12 one of which is removable. Journaled axially of this side wall is the shaft lOl, provided at one side with the radial blade ll3 which sweeps about the wall. interposed between the walls 111 and 112 at one point is the hollow valve box 114 separated by partition 115 into two charm bers which communicate respectively with ports 116, 117 formed in the wall 116. Mounted in this valve box are valves SO -51, respectively, generally similar in construction and mode of operation to the valves 56 and 51 illustrated in Fig. 42, except that instead of providing the valves with an operating yoke l have here illustrated the two sides of the piston 113 as provided with leaf springs 120 which, upon reaching the end of each oscillation, shift the valves and reverse the direction of motion in the same manner as described in connection with Fig. 4. The conduit 25 is connected with the port 117 which leads to the inlet valve chamber, while the port 116 communicating with the outlet valve charziber joins the pipe 69' which returns to the pump. There is no connection from the shaft 101 to the tub but only to the dasherl During the operation of the dasher the tub is at rest, supported by the top of the sleeve 90; during the rotation of the tub by the turbine 67* the shaft 101 is at rest i,

although the dasher is best removed. The'outlet port of the pump 92 is connected to conduit 121 which overhangs the washing container so as to produce, during the washing operation, a constant circulation of liquid which in conjunction llb with the agitation of the dasher causes all floating scum to be washed through the apertures 99 and deposited in the casing where it is left. The employment of two separate pumps enables the complete separation of the washing liquid from the working fluid, the vertical pipe 12 acting as a reservoir to take care of different amounts of liquid required at different parts of the stroke of the piston, but it is' possible to use only a single pump and employ the washing liquid in the opera ating devices as already described. Also it is possible to locate both pump and turbine inside one and the same chamber as will next be described.

In Figs. 13 to 17 inclusive I have shown the identical washing machine set forth in my ap-.

plication filed January 22, 1923, Serial No. 614,080. This comprises an upright cylindrical casing 1 carried by the frame 7 and legs 8, and bolted to this frame concentrically with this casing is the casing of a centrifugal pump having at its upper margin a circular flange 131 tightly applied to the bottom of the casing, this bottom being cut away inside the flange to permit free access to the pump chamber. Leading be grasped. Swiveled to the branch 134 is an upright pipe 137 which passes through a suitable collar 138 secured to the tub rim and terminates in an overhanging spout 139.

- Secured inside the casing bottom opposite the flange 7 is a ring 140 to which is secured a spider 141 having an upwardly extending central boss 14.2. Secured to the bottom face of the pump casing 130 are a plurality of arms 143 to which is attached an electric motor 10 having a vertical shaft 144 attached by the flexible joint 145 to the pump shaft 146 which'enters the pump casing by way of the packing gland 147 and has connected thereto a suitable impeller shown in section in Fig. 16. In its present shape this impeller comprises a fiat circular plate 148 having a central hub 149 receiving the shaft 146, and a plurality of blocks 150 carried by the upper surface of this plate and spaced from the hub to form a central chamber and also spaced from 3 each other to form a plurality of spiral outlet passageways 151. I have shown the tops of these passageways as covered by a shroud plate 152, and the interior of the pump casing as formed with a circular rib 153 which projects rather close to the edge of this shroud plate and defines a circulation channel which communicates with the outlet pipe 132.

Journaled in the boss 142 is a vertical shaft 155 above the shaft 146 and having secured-to its lower end a suitable turbine rotor one form of which is shown in Figs. 13 and 17. In this particular embodiment the rotor comprises a cir cular face plate 156 having on its lower surface a plurality of curved vanes 157 these vanes being presented toward the upper surface of the impeller, and the surface of the plate 156 being shaped to define a smooth sweep into the central cavity of said impeller. The periphery of the plate 156 is spaced from the ring 140 a sufof a flexible gasket 168 of an intermediate sleeve 170 which loosely suresaeae ficient distance to permit free ingress of liquid from the casing interior.

The shaft 155 is formed at its upper end with a prismatic portion 153 which projects above the boss 142 for the reception of the rotating tub in which are placed the articles to be washed. This tub comprises a bottom 160 and side wall 161, the whole terminating in a top flange 162 located slightly below the top of the casing 1 This side wall is preferably formed with'an 'external bulge intermediate its top and bottom, the bulging portion being provided with a plurality of liquid discharge apertures 163. I also find it advantageous to form the sides of the tub with vertical corrugations as shown. at 164 in Fig.

18, these being so arranged as to intersect said discharge openings 163. This arrangement keeps the clothes from packing tightly against the walls thereby always permitting free discharge of the liquid during the spinning operation, the

side well being preferably imperforate below the level of the apertures 163 so as always to maintain sumcient liquid in the tub for the washing operation. This corrugated metal also facili- -tates the manufacture of the tub with the flaring' shape desired since the flexibility imparted.

thereby enables the a rectangular blank.

The hub bottom is here shown as formed with a vertical axial depending sleeve 165 secured to the bottom 160 and braced by the false bottom 166, said sleeve being, formed at its lower end with an outturned flange 167 connected by means to the outturned flange production of the tub from rounds the riser 142 and has at its upper end a socket 171 for the upper end of the shaft 155. This arrangement permits the tub to gyrate freely without vibration in case the load therein be unbalanced in any way.

The washing mechanism in this embodiment.

comprises an upright cylinder 175 having at its lower end a constricted portion 176 terminating in an aperture 177 defining a seat for a rubber ball 178 to which is attached a vertical stem 179. Slidably mounted inside this cylinder is a plunger 180 having a central hollow hub 181 in which the stem 179 is loosely received.

At its upper end the stem terminates in a head 182 between which and the plunger is interposed a spring 183. A valve controls the flow of liquid from the pump casing to this hydraulic washing device.

The operation of this last described washing machine is as follows: the tub is filled with washing liquid in suflicient quantity to overflow through the apertures 163 and form a substantial layer in the bottom of the casing. The mo tor 10 being started and the valve 185 being open (the valve 135 being closed) the effect of the pump is to deliver a forceful stream of water of very considerable volume into the cylinder 175. The ball 178 being seated the effect of the water pressure is to elevate the plunger 180,

compressing the spring 183 until the upward plunger must be sufficient to cause it to fall when the aperture 177 is open, and its weight can be augmented by a spring if desired. This discharge continues until the ball 178 arrives near its seat whereupon the suction causes it to close 59 quickly whereupon the action is repeated. In this way a pulsating discharge of coherent masses of water are produced which has the effect of thoroughly agitating and pounding the clothes and washing all floating scum through the apertures 163 into the outer casing where they are retained since the pump takes only from the of the turbine in order to reach the central chamthe casing into the pump, passing the vanes 15'? of the turbine in order to reach the central chamleer of the impeller, produces a slow and steady rotation of the tub whereby successive operations of the washing device are applied to an everchanging portion of the tub contents. The size and number of apertures 163 is so adjusted that the desired amount of liquid remains in the tub at all times during this part of the operation, and the elevation of the tub above the bottom of the casing is such as to accommodate all the liquid there oeneath.

"if new the valve 185 he closed, the liquid displaced by the pump impeller can no longer esall cape, but is turned back upon itself with the production of a very powerful swirling motion adja cent the impeller which acts upon. the vanes 1.57 and readily imparts to the tub a high rate of roion thereby iorcihly ejecting all the liquid through the apertures 163.

"While in this last embodiment have shown the pump impeller and turbine rotor as located inside the same casin for purposes of simplicity, it will he understood that separate casings can employed therefor as in the other modifications herein shown; andwhile have shown the washing effect as produced by the employment oi. a forceful stream of water, and without the interposition of paddles, blades, hells. heaters or other mechanical accessories, it will be obvious e pounding sheet can he produced if de= secondary manner as well as a priroary Such a hydraulically operated rythmically moving mechanical pounder is illustrated in Fig. wherein the end of spout its is provided'with reciprocating device which converts the energy of the liquid into mechanical reciprocation oi an inverted cup 190. This suction cup is carried by a vertical piston rod 3.91 secured to a piston 192 in a vertical cylinder l93 carried by the hollow head 19% and surrounded by a closed outer shell 195. Formed in this head are two liquid passageways 196 and i9? shown in Figs. 22 and 23, one, we conununicating with the bottom end or the cylinder 193 and the other, 19?, communicating with the annular space between the cylinder and shell and thus with the upper end of the cylinder.

Located adjacent the passageways 196 and 197 is a butterfly valve 198 which when in one position establishes communication between the spout 139 and the passage 19'? as shown in Fig. 22, meanwhile establishing communication betweenthe other passage 1% and a downwardly facing discharge port 199; or when reversed into the dotted line position shown in Fig. 22 interchanges those connections and causes the spout 139 to communicate with the passage 1% and the pas sage is? to communicate with the discharge port 1%.

For operating this valve I have shown a kind of crank 200 connected therewith and cooperating with a kind of spool 201 slidaloly interposed between the lower end of the rod 191 and the fixed bearing 202 carried by the head 194. A

paiT oi' spaced flanges 203-203 engages this to bring all parts thereof repeatedly Llaltered reversing the position of the valve 19% and reversing the direction of motion.

In Fig. 19 I have shown the pump casing 13 ashaving its axis horizontal and its rotor shaft 11"- provided with a pulley which is belted to the driving policy 210 of the motor 211. K have also shown the washing container as having side walls 161 of the same shape as in it, but removahly resting on a circular tray 212, the bottom of which is provided with turhhie hlades 213 locawd to receive the liquid discharge from a fixed nozzle 214i projecting into the side of the casing 1 from the upright pipe 13'? which leads from the outlet of the motor casing 7.3 to the spout 139, the latter being provided with-a control valve 185 whereby the action of mechanism can he arrested. While the valve 185 is open the discharge from the nozrle 21% is much wealrened with the result that ti vclves comparatively slowly, although so When valvewith a coruiectin leer-c .Jli ding outside of the sleeve 215 connected th eeve 219 depending ens 'hetr withinte cos .on ofa flexible washer to pe t a cert in amount of gyration of the device. is obvious, of course, that other and si or supporting, pivoting, controlling, etc. devices can be In all the cparatus herein described sential considerations are tie o oration or washing device oi the rhytlunical sor ing (and sometimes also an extractor of the cen= trifugal type) by fluid pressure produced by an electrically driven pump carried by and forming a part of the machine itself, regardless of the nature, shape, position or material or? the wash ing devices, regardless of the shape construc= tion of the centrifuge container, regardless wheth= er the washing and centrifugal actions take place in the same or dinerent compartments, and re gardless whether the driving devices he operated by the washing fluid or by a different fluid. expression rhythmically operating is employed as covering all intermittent repetitive means whether they contain mechanical agitators, gy= rators, pounders, or heaters, or whether they opcrate solely by the intermittent discharge of liquid,
